The present study was carried out to investigate the routine use of second-generation antipsychotic drugs in the Italian psychiatric care system. Seven outpatient psychiatric services enrolled a consecutive case series of patients who were being treated, or had started treatment, with clozapine, olanzapine, risperidone, or quetiapine. Information on sociodemographic and clinical variables, current psychotropic drug use, side-effects and past use of typical drugs was collected. In addition, patient symptoms and functional status were evaluated by the Health of the Nation Outcome Scale. Patients receiving off-label prescribing of second-generation antipsychotics were identified. A total of 209 patients were collected. In comparison with patients receiving other second-generation antipsychotics, living in residential facilities, unemployment, long psychiatric histories, and problems with activities of daily living and living conditions were more common in clozapine-treated patients. Nearly 80% of patients receiving clozapine had schizophrenia compared to less than 50% of those receiving other second-generation antipsychotics. Overall, 109 patients (52%) received off-label prescriptions of second-generation antipsychotic drugs. This survey indicates that clozapine was mostly reserved for severe cases and poor responders; the high rate of off-label prescriptions highlights the gap existing between recommendations derived from randomised clinical trials and the current use of drugs.

Abstract

The present study was carried out to investigate the routine use of second-generation antipsychotic drugs in the Italian psychiatric care system. Seven outpatient psychiatric services enrolled a consecutive case series of patients who were being treated, or had started treatment, with clozapine, olanzapine, risperidone, or quetiapine. Information on sociodemographic and clinical variables, current psychotropic drug use, side-effects and past use of typical drugs was collected. In addition, patient symptoms and functional status were evaluated by the Health of the Nation Outcome Scale. Patients receiving off-label prescribing of second-generation antipsychotics were identified. A total of 209 patients were collected. In comparison with patients receiving other second-generation antipsychotics, living in residential facilities, unemployment, long psychiatric histories, and problems with activities of daily living and living conditions were more common in clozapine-treated patients. Nearly 80% of patients receiving clozapine had schizophrenia compared to less than 50% of those receiving other second-generation antipsychotics. Overall, 109 patients (52%) received off-label prescriptions of second-generation antipsychotic drugs. This survey indicates that clozapine was mostly reserved for severe cases and poor responders; the high rate of off-label prescriptions highlights the gap existing between recommendations derived from randomised clinical trials and the current use of drugs.
